られるようになつた。 In the configuration shown in Figure 2, polyester is used as the dyeable polymeric substance, and tetrafluoroethylene with a particle size of 1000 Å and air bubbles 3 with a diameter of about 0.1 micron are dispersed as the polymeric substance 4 that is incompatible with the polyester. An image receptor for transfer type thermal recording was prepared with a dyed layer 2 having a bulk specific gravity of 0.9 and a thickness of 25 microns.
When the relationship between the applied pulse width and the saturated recording density was measured, the results shown in FIG. 4 were obtained. The saturated recording density is a value obtained by measuring the density on the image receptor after thermal transfer using a reflection densitometer. The comparative example in the same figure is bulk specific gravity.
This is an image receptor equipped with a dyed layer consisting only of 1.4% polyester. As is clear from the figure, when a dyed layer with air bubbles dispersed therein was provided, the saturated recording density increased and the characteristic curve became linear and smooth. As a result, images with uniform gradation can now be obtained.
